    Abstract - (Show below) - (Hide below)

    IEC 61746-2:2010 provides procedures for calibrating multimode optical time domain reflectometers (OTDR). It covers OTDR measurement errors and uncertainties. The test of the laser(s) source modal condition is included as an optional measurement. This standard does not cover correction of the OTDR response. Keywords: calibrating multimode optical time domain reflectometers (OTDR)
